of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

My invention relates to a machine for use in removing the lint fromcotton-seed.

The invention consists in features of novelty hereinafter fullydescribed, and pointed ent in the claims.

Figure I is a perspective View of my improved machine. Fig. II is anelarged sectional View taken' through the toothed carrier-Wheel and thespring-controlled lint-removing plates. Fig. III is avertical sectionalView taken approximately on the line III III, Fig. I. Fig. IV is anenlarged sectional View taken on the line IV IV, Fig. III. Fig. Vis anenlarged sectional view taken on the line V V, Fig. III.

l designates the frame of the machine, on which housing-walls 2 aremounted.

3 is a feed-hopper mounted between the walls 2 at one end of themachine, and 4 is a discharge-spout located at the opposite end of themachine.

Mounted in bearings on the frame 1 is a On the shaft 5 is a wheel 7,provided on its circumference with a series of toothed bands 8. Thesebands are preferably secured to the rim of the wheel by means of rivets,as illustrated in Fig. V. The teeth of the bands are angular in shape,Similar to saw-teeth, and all project in like direction.

9 designates plates mounted on cross-rods 10, secured in thehousing-walls '2, said rods constituting hinges on which the plates maybe swung. Springs 11, that bear thereagainst and are connected totransverse rods 12, seated in the housing-Walls. Each hinged plate 9 hassecured to its under side a sheet-metal facingplate 13, provided withprotuberances 14, formed by punching a portion of the plate The plates 9are controlled by4 outwardly fromone side thereof, thereby producingaroughened edge to the protuberance. The cotton-seed to be delinted isfed into the machine at the hopper 3, and the toothed carrier-wheel 7being revolved in the direction of 'the arrow, Fig. III, carries thesaid seed upwardly beneath the plates 9, in which movement the seed isbrought into contact with the protuberances 14 of the facing-plates 13,owing to said facing-plates being held close to the circumference of thecarrierwheel. The roughened protuberances act upon the seed in itstravel to pull the lint therefrom, gathering the lint until such time asthe protuberances have become clogged by a considerable collection oflint, when the `lint is dragged therefrom in the travel of the seed.

15 designates combs fixed to the housingwalls 2 and adapted to retardthe movement of the seed in order that it may receive sufficient contactwith the lint-removing Wheel 7 to result in the lint being efficientlyremoved from the seed.

16 designates an air-box to which an airconducting pipe 17 leads throughbranch pipes 18. The pipe 17 may lead from any suitable source ofcompressed-air su pply,such

as a reservoir 19,v (see Fig. IIL) from which compressed air may beconveyed throughthe pipe 17 and its branches 18 into the air-box 16 toeffect a pressure against the seed as it passes the combs 15, therebyholding the seed against the periphery of the carrier-wheel instead ofits being permitted to be thrown away from said wheel by centrifugalmotion in the rapid revolutions of the wheel. As the seed reaches theoutlet-Spout4. it passes from the machine therethrough, while the lintis conveyed with the wheel by adhering to the teeth of the bands 8.

2O designates a rotary brush located in a housing 21 and mounted upon ashaft 22, provided with a drive-pulley 23, that receives power from theshaft 5 through the connection of a belt leading to a pulley on saidlastnamed shaft,l0cated at the opposite'end thereof from that upon whichthe pulley 6 is mounted. The pulleyT 23 is of less diameter than thepulley on the shaft 5, with which its IOO driving-belt connects, sucharrangement being provided for the purpose of acquiring a more rapidrotation of the shaft 22 than that of the shaft 5.

24 designates a fan-housing located beside the brush-housing 21 andhaving an eye communicating With said brush-housing. In this fan-housing is a fan 26, mounted on the shaft 22. The fan-housing 24 i-s providedwith an outlet 27.

In the revolutions of the carrier-wheel 7 the lint is carried therewith,as explained, after the teeth of the bands 8 pass the dischargespout 4.The rotary brush 2O revolves in contact with the toothed bands 8,traveling at a higher rate of speed than the carrier-wheel, and actsagainst the toothed rims to eiectually remove the lint into thebrush-housing 21, from which it is collected by the fan 2G, being drawnthro ugh the eye 25 and discharged from the fan-housing through theoutlet 27, from which it may be conveyed to any desirable location anddeposited.

I claim as my invention- 1. In a cottonseed cleaner,the combination of asuitable frame, a wheel rotated in said frame and having upon itsperiphery sawteeth having their lateral dimension extending in thedirection of the Wheels axis, and with cutting edges presented in thedirection of the wheels rotation and holding-plates arrangedtangentially to the wheel and formed with pockets or depressions ontheir inner faces by which the seed is held and retarded while thesaw-tooth edges cut the lint there from.

2. In acotton-seed cleaner,the combination of a suitable frame, a wheelrotated in said frame and having upon its periphery, sawteeth having`their lateral dimensions extending in the direction of the Wheels axiswith cutting edges presented in the direction of the Wheelsrotation,means for delivering seed to and discharging it from the wheellocated approximately at opposite ends of the Wheels longitudinaldiameter, and holding-plates arranged tangentially over the upperportion of the Wheel and formed with pockets or depressions on theirinner faces by which the said seed is held and retarded While thesaw-tooth edges cut the lint therefrom.

3. In a cotton-seed cleaner,the combination of a suitable frame, a wheelrotated in said frame, and having upon its periphery, sawteeth havingtheir lateral dimensions in the direction of the wheels axis, and withcutting edges presented in the direction of the Wheels rotation, androughened holdingplates arranged tangentially over the upper portion ofthe Wheel providing gradually-reducin g passages between them and thewheel, and leaving narrow escape-passages between their free ends andthe saw-teeth.

4. In a machine of the character described, the combination of arevoluble saw-toothed carrier-wheel, means for holding the material tobe acted upon in contact with the periphery of said Wheel, anair-receiving box arranged at the periphery of said wheel, and means forconveying a supply of air to said box, substantially as and for thepurposes set forth.

5. In a machine of the character described, the combination of a toothedcarrier-wheel, housing-Walls, means for holding the seed operated uponto the periphery of said wheel, an air-box, and means for conveying asupply of air to said box to retain the seed operated upon against saidwheel, substantially as described.

6. In a machine of the character described, the combination ot' atoothed wheel, housing- Walls, plates provided with protuberances hingedbetween said walls, springs arranged to hold said plates toward theperiphery ofV
